Rmxp Sprite Rotation methods.

[Chaosg1]

I don't know if there is what i am asking for but....
Does RMXP have sprite rotation methods?
Like rotate the sprite in any angle?
IF not would it be possible to create such script?

The Sprite class has a rotate method, but it only rotates from the top-left corner of the sprite.

I am working on a few rotate method in the Bitmap class (pixel by pixel transfer ), so I will add something for the Sprite class as well.

psst Tricktster, you can change the ox and oy of the sprite to move the origin of rotation

 

[Chaosg1]

@Seph: ok I will wait for your script edition whatever. because i need it to be pixel by pixel. Since this is for a 360º engine,it will rotate the sprite depending on the slope angle(still working in the formula to check the slope angle lol.

Note: when i say 360º engine it doesn't mean 3d... I mean you can make loops and other things. If I ever can accomplish this...

Trick: with that thing you said... can I rotate the sprite in angles,smoothly?

Do, sprite.ox = sprite.bitmap.width / 2, sprite.oy = sprite.bitmap.height / 2. This sets the origin of the sprite to the centre. Now when the image is placed it is placed at the centre (not the top left corner) and when you set the sprite.angle (degrees) it rotates around the centre of the sprite, if you want it to be smooth just add a few degrees each frame.

angle
The sprite's angle of rotation. Specifies up to 360 degrees of counterclockwise rotation. However, drawing a rotated sprite is time-consuming, so avoid overuse.

It may lag if you use it every frame

What if it was called as a new thread? (not exactly sure what threads are all about)

@Chaosg1: making 360 degrees system is in my opinion pointless. let's assume the hero sprite would turn around at a speed of 1 deg/frame - making a full circle would take 9 seconds. how "undynamic" is that! for a great control over rotating the sprite I'm sure 5 or 10 deg/step would surely be enough

 

[verballydecapitating]

Well, if he uses the mouse script the player could just face the cursor.

 

[Chaosg1]

Thanx for replying... But when i said smooth, I wasn't saying one degree per second... i just was saying like so that the character doesn't jump when rotating... hard to explain i hope you get it..
@verbally i will try that....

 

[Chaosg1]

I just wanted to know one thing, is this possibly with the player? becuase i can't seem to make it work....

 

[GreatSuperheroPikachu]

i think 360 degree engine requires you to make a 3d object like for example, a house

 

[arev]

nay... I think it doesn't even need 360 sprites, as the difference between them wouldn't be really noticable.

 

[Chaosg1]

I wont need any more sprites than the player if i can make the rotation work, that's why I am asking for help.

I hope you can make the engine, maybe it should rotate at say 10 degrees or so and try to make it arond 12FPS just so it dont look like its overlagging, its a great idea though.
